for .NET · Python · TS agent teams on Progress AI Observability

Security evals from your agent's real behavior.

evsec reads a sample of your agent's real traffic and writes evaluators and attack test-sets tuned to what it actually does: the tools it calls, the data it touches, the policies it runs under. It stores nothing.

evsec generate --demo runs on a bundled trace — no key, runs locally, nothing stored

Generated from your real spans, covering your agent's actual tools. Every pack is tagged to OWASP LLM Top-10 and the EU AI Act.

Why it's different

Every security test answers one question: how does it know what to test?

There are four answers — and only one reads the ground truth.

Fixed packs

Guess from a template

Garak and template scanners ship a static payload list. They don't know your agent has an IssueRefund tool gated behind a ReadPolicy check — so they can't test that line.

Endpoint probing

Fire blind at the app

Scanner "discovery" agents probe the live endpoint and infer a profile from responses. They see the surface, not the internals — and can't know a tool exists until they stumble into it.

Code analysis

Read the source

Static agent-graph scanners map tools from code. They know what the agent can do — not what it does: real policies in retrieved context, real data shapes, real user pressure.

evsec · trace-grounded

Read what it actually did

evsec reads a sample of real production spans — the true tool inventory, system prompt, retrieved context, and policies — then writes a judge and an attack set for your actual attack surface.

What it generates

Read. Generate. Run.

01

Read

Pull real spans over MCP — tools, prompt, policies.

02

Generate

Scrub PII, then write evaluators & attack sets.

03

Run it in Progress Observability

Paste the judge or import the CSV at observability.progress.com — the platform runs it and keeps the findings.

evsec — OrderSupportAgent-sensitive-tool-use

Why this config. Frame 'tool_call' mode enumerated from this agent's real sensitive tools: IssueRefund, RememberFact, ForgetMemory. The pack a generic evaluator structurally cannot write — it needs the agent's actual tools and dependency rules, both from the spans.

Takeaway 01

Evaluator packs

An LLM-judge prompt + span config you run continuously in Progress. Install one and it backfills findings across your past traffic.

Takeaway 02

Attack datasets

Adversarial test rows built from your real tools and policy — refund-under-pressure, data exfiltration — graded by the matching evaluator.

Stateless by design

No traces, no findings, no history. Spans are held in memory for one generation pass, then discarded. The only artifacts that persist are the packs you take — owned and stored by you, in Progress. PII is scrubbed before anything reaches a generation model.

Mapped, not overclaimed

  • OWASP LLM Top-10 — every pack tagged to its category.
  • EU AI Act — robustness content maps to Art. 15; monitoring evaluators support Art. 72 evidence once run in Progress.
  • Honest language — evsec generates test and monitoring content; it doesn't make you "compliant" and attests nothing.
FAQ

Questions, answered plainly

Which model does the generation, and does my trace leave my environment?
evsec reads spans over MCP, scrubs PII locally, then holds them in memory for a single generation pass and discards them — nothing is stored. If an optional generation model is configured (for attack variety), only scrubbed content is sent to it; without one, packs are built from deterministic templates.
What if I'm not on Progress Observability yet?
Run evsec generate --demo — it generates a full report from a bundled customer-support trace with no key and no account, so you can see exactly what evsec writes. Live mode (--service) reads your own traffic and needs a with-content MCP key from a Progress workspace.
What does it cost?
evsec is free during early access — we're onboarding design partners who want a voice in the roadmap. The generated packs run in Progress Observability, which is priced separately by Progress.
Does evsec store my data or findings?
No. It's a stateless generator: no traces, no findings, no history. The only artifacts that persist are the packs you choose to take, owned and stored by you in Progress.
How is this different from Promptfoo, Garak, or a scanner?
Those guess at your agent from a template, a blind probe, or its source code. evsec reads what the agent actually did in production. Full breakdown on the trace-grounded security evals page.
Early access

See what it writes for a real agent — right now.

One command generates a full evaluator pack and attack set from a bundled customer-support trace, on your machine. No signup, no key, nothing stored. Design partners get direct support and a real voice in what gets built next.
